Well, it depends on your preferences/capabilities, but Staff View, despite it's quirks, works for me.

 
Thanks Erawax, but Staff View is quite limited when you need a precise editing of MIDI, where you have to work with ticks, multiple simultaneous tracks, several controllers, etc.
That is the purpose of PRV.
The only regret is having to live with this limitation of PRV that consumes me a considerable time and also induces me to make mistakes.

Ah, the perfect excuse to upgrade to new SONAR! Controller lanes now display a "shadow" extending to the right of the controller event that persists until the next controller event changes its height. Gotta be a pic somewhere around here.
 
Here's a quickie example:
 

Yes, it's one of the various MIDI PRV improvements.

Yes, that's exactly what I'm looking for a long time!
But where active this format in Sonar X3?

It's not in X3. It's part of the various MIDI enhancements in the new SONAR.

I know it is not the PRV but the events list is very informative.

Yes, Event List is informative, but not useful for visual edition, as PRV.
And from what I saw, the only way to get what I'm asking, is to go to the new Sonar ... again ... 

TBH I'm never really spent the time looking at the new "improvements" however I did upgrade from X1 Producer, so there is probably a lot under the hood I'm unaware of.
